'Restrain' in the Bible

Now I have told him that I am about to judge his house forever for the sinful behavior which he knew [was happening], because his sons were bringing a curse on themselves [dishonoring and blaspheming God] and he did not rebuke them.

When Samuel hath seen Saul, then hath Jehovah answered him, 'Lo, the man of whom I have spoken unto thee; this one doth restrain My people.'

and blessed is thy discretion, and blessed art thou in that thou hast restrained me this day from coming in with blood, and to restrain my hand to myself.
